Not really my list found it on that blog. There is a part2 version too. I checked those cars in my area with the exception of the ferrari I found all the vehicles listed for under 20k.
He or she didnt mention it explicitly, but when you are talking about buying a used car. You are quite aware or should have taken this into consideration imo! There is nothing wrong with buying or owning a carmy in general, but when you are comparing it with the mentioned list of cars, carmy just doesnt quite fit in here, other than when you are strictly talking about price. The NSX, M or any F cars or even Corvette have rich racing heritage behind each of them, not only in design, but all of them are very unique in its own right. After all, these cars are made for pure driving enthusiasts...just my 2cents.
You can get a brand new Ducati 1198 for well under 20K. None of these cars can touch that with a 10 foot pole.
